The APUs in this group can all be matched with a discrete graphics card from AMD to enable “Dual Graphics” functionality. This is essentially a CrossFire solution using the onboard graphics and the discrete card. The HD 6670 and below cards for the 6000 series and the HD 7670 and below for the 7000 series can all be matched with an APU. This should in theory double performance in graphics heavy applications, and in reality it seems to work pretty well. The only issue that we really see is that for a few dollars more a user can get a 7750 (which will not work in Dual Graphics mode) and outperform a DG enabled A10 5800K + HD 7670.

I believe he is meaning 77xx cards cannot crossfire with 76xxAPU's. I thought 75xx on up cards couldn't crossfire at all with 75xx or 76xx APU's since the APU architecture is more in line with the 65xx-66xx series.

Now awaiting of new system - A10-5800K on new 85X chipset.
Arrival at 10 march. Also have 7750 in Intel comp.
Will try to copulate Trinity and 7750.
But actually not nessesary - new AMD system planned to be downclocked HTPC in normal miditower case.

1370 to 2761 isn't a small jump. A 5800k + 6670 would net about 2500 so it's marginally better but with the 6670 going for $65 getting a 7750 for dual graphics surely doesn't look worth it. Still it's one of those things that are cool just because they work.

He's using 1333Mhz RAM though... with faster RAM he could get better results... maybe that's what's holding him back.

Still working on fine tuning my overclocks, but everything is running well. Able to play borderlands 2, grid 2, blacklight, on high. GTA IV on medium (video RAM bitrate really shows its weakness on this game.) Everything I play is on 1080p.

Sorry pulled over the screenshot from my thread on another forum. If you look at my CPU-Z validator you can see its a Trinity 5800K. The GPU-z shows dual graphics 7760D and 7700 (not sure why it doesn't show 7750.)

i have read consistently across the interwebz that the 7750 works, certainly with Richland, didnt know it worked for trinity though, next question is can you put two 7750's in there and go hybrid trifire?
